Created a website, submitted sitemap and google indexed pages right away. I tried searching for related keywords and indexed pages did indeed show up in google search results. But after couple of days pages still show as indexed (visible gsc and site:website) but when I test and search related keywords the pages do not show up in google results any more. Content is original, so are images and I tripple checked everything and there seems not to be any problems. P.S. pages do show up when you search for related keywords on bing and other search engines.
Actually same thing happened to my older website. It was working great and then after a year or so the indexed pages still showed up as indexed but did not respond to keyword search and did not show up in google results any more.
